Help in PlayVision NBA2k10

Hi to all..
I am trying to use the play vision feature of NBA2k10 but i can't seem to make it work. i can call plays but the floor markings does not appear. can any one please guide me thru this. appreciate any help..

i have already tried searching for a solution but seems like there is no thread about this yet.

thanks in advance

go to coach>settings>then set playvison on show all(or something like that)
